No. I checked the source for fread (in DJGPP/SRC/LIBC/ANSI/STDIO), which 
does not limit in any way the number of bytes read. Also, I wrote a small 
program which smoothly read 1000000 bytes with one fread().

What did you use to open your file ?
It should be
fopen("myfile.sth","rb");
                   ^^^^^
on my machine, if you say :
fopen("myfile.sth","r");
                  ^^^^^ 
your file is opened as a text file, and fread() does not work as you 
wish... (I think this default attitude can be corrected by fixinf 
something in a .h header).^
